を持っている。This type of capacitor was first published in patent application No. 5 in 1982.
It is known from the publication No. 2213. The metal layer of aluminum is then deposited in a vacuum or produced by cathodic sputtering and has a thickness of, for example, 30 nm.

にあるマスクによって作られる。In the case of a capacitor with, for example, 100 glow polymer layers and aluminum layers each, the layers are bonded to each other by the material itself. The necessary definition of the alternating layers is created by the overlying mask.

される。In order to make the capacitor as large as possible, the dielectric layer must be made extremely thin, and its thickness must therefore be reduced to 0.
It is necessary to set the thickness to 1 to 05 μm. To make this thin layer reproducible, aluminum, which forms an insulating oxide as a so-called valve metal, is used as the coating metal.

因するものである。The duration of this insulating low F decreases as the temperature j-law increases by -1, and furthermore, the insulating low F shows a certain dependence on the composition of the dielectric layer. This decrease is attributed to the movement of aluminum atoms into the dielectric layer, ie, thermal transfer.
本発明の目的は、最初に述べた形式のコンデンサを、熱
移動による絶縁低下が起らないようにすることにある。The object of the invention is to make a capacitor of the type mentioned at the outset free of insulation degradation due to heat transfer.
この目的ｉ４本発明だよれば、熱移動を防止するためア
ルミニウムからなる金属層が１５ないし１０重量係の銅
を含むことによって達成される。According to the invention, this objective is achieved in that the metal layer made of aluminum contains 15 to 10 parts by weight of copper to prevent heat transfer.
アルミニウム層は２５ないし４重ｔｔ％の銅を含むのが
好ましい。Preferably, the aluminum layer contains 25 to 4 weight tt% copper.
本発明のコンデンサは、温度および時間に依ｆｌした絶
縁低下そのものが、高温での数千時間の貯蔵後でも決し
て起らないという利点をもっている。The capacitor of the invention has the advantage that temperature- and time-dependent insulation degradation itself never occurs, even after thousands of hours of storage at high temperatures.
銅含有率が１５重敗係以下では、熱移動は完全には阻市
でき詠−刃鋼が１０重量係を超えると金属層が脆くなる
。When the copper content is less than 15% by weight, heat transfer is completely inhibited, and when the copper content exceeds 10% by weight, the metal layer becomes brittle.

−ドを防止する目的をもっている。A renewable electric capacitor in which the metal layer is made of an alloy of aluminum and copper is already known (Patent Application No. 96466 of 1971), but it is a capacitor in which the winding is made of a metalized synthetic resin film. It is related to. Insulation degradation due to heat transfer has not been observed in this kind of capacitors, and the metal layer disclosed therein, consisting of an alloy of aluminum and copper, is resistant to damage when used in hydrogen- and/or oxygen-containing atmospheres. -The purpose is to prevent the capacitance of the capacitor from becoming low.
